Application filed January 9, 1908. Serial No. 410,029.

objectof my invention being to permit of the ad ustment of these blade-carrying mem-.

bers to suit wide or narrow rows without causing any material change in the relation of the cultivator blades to one another, or to the rows of plants between which said blades operate. This object I attain in the manner nereinafter set forth, reference be ing had to the accompanyingdrawings, in which Figure 1 is a view, partly in longitudinal section but mainly in side elevation, showing surlicient of a double row cultivator to properly illustrate those parts of the same to which my invention particularly relates; Fig. is a view, on a reduced scale and mriuly in top or plan view, but with a portion shown in horizontal section on the line (z-a, Fig. 1, and with the axle and rigid framework of the machine omitted and the wheels shown by dotted lines, Fig. 3 is atransierse section on the line ob, Fig. 1, also on a reduced scale and looking toward the front end of the machine, and Fig. 4 is a sectional view, on an enlarged scale, of one of the elements of the machine.

The machine has the usual bowed or arched axle 1, carrying the supporting wheels and the main draft bars 3, the latter having a transverse bar 4, uponwhich are mounted the devices for supporting the front portions of the structures which carry the cultivator blades. As both of these structures are substantially similar a descriution of one of them will suffice.

Each structure comprises two bars, each consisting of front and rear members, pivoted together, the cultivator blades 7 being mounted upon the rear members 5 and 6, of the bars and said members being disposed in V-form with the open end of the V at the. front. Said rear members of the bars are pivoted togetherat the rear by means of a pivot pin 9 engaging brackets 10, one on cacl'i member, as shown in Fig. 2, and the member 5 has an upturned forward end 11, which is free to turn in a bearing in a bracket 12 carried by the rear end of the forward member 13 of the bar, the upturned end of the member 5 being vertically supported in said bracket by means of a pin 13 passing through saidupturncd end and resting on thetopof the bracket,

as shown in Fig. 1, or by any other avail able means for effecting such support. The front end of the member 6 has a preclsely similar connection with a bracket 12 at the rear end of the forward member 14, of the A other bar of the pair, as shown in Fig. 2.

The front end of the member 13 is pivotally mounted ina box: 15 which is bolted to the rear ends of links 16 whose front ends are pivotally connected to brackets 17 on the ported vertically by engagement with a yoke 19 which is bolted to theunderside of said transverse beam 4, whereby a limited amount of lateral adjustment of the front end of the transverse bar 4, the links being further suplever having a rod 22 whereby it is connected W to an adjusting lever 23 suitably mounted upon one of the longitudinal beams 3 of the machine, as shown in Fig. 1.

The forward end ofthe member 14isbent inwardly and passes through a carrier .24, which is mounted so as to be free to slide laterally upon a rod 25 extending across the front of the machine and supported by hangers 26 depending from the transverse beam 4, n

as shown in Figs. 1 and 3, said sliding carriers having dependinglegs between which is confined any availableform of gripping device 27, whereby the inwardly bent forward end'of the member 14 can be adjusted laterally in respect to the sliding carrier and secured in any of its desired positions of adjustment, whereby two means of lateral adjustment for the member 14 are provided,

the first being its'lateral adjustment in respect to the sliding carrier 24 and the second the sliding movement of said carrier on the transverse rod 25. The latter movement is effected by connecting the carrier, by means of a rod 29, to the forward end of a lever 30, which is suitably pivoted to a stud 31 on the main longitudinal frame of the machine, shown in Fig. 1.

The forward portion of each of the members 5 carries a bracket 32, through which passes the lower end of a lifter rod 33, which engages the bracket by means of a transverse pin at the bottom, or in any other suitable way, in order that lifting movement of the rod 33 will always be transmitted to the member 5, while lifting movement of the latter, independently of the rod, such as might be caused by an upward thrust upon the cul tivator blades, will be permitted, such move ment being restrained, however, by the pressure of a coiled spring 34, which is interposed between the bracket 32 and a shoulder 35 on the lifter rod, the upper end of said rod being hung to one arm of a lever 36, whereby its vertical movements are effected.

In order to transmit the lifting strain from the member 5 to the member 13, and thereby relieve from strain the pivot pin 11 between these members and prevent the same from becoming jammed in its bearing because of such strain, the bracket 32 has secured to it a forwardly projecting arm 37, whose forward end is bent into segmental form and bears against a segmental arm 39 bolted to the member 13, the arms 37 and 39 being held in contact with each other by means of a bolt 40, but one or both of the arms being slotted so as to permit swinging movement of the member 5 in respect to the member 13 while still providing a rigid connection between the two members as regards vertical movement. By reason of this construetion, the members 13 and 14 may be adjusted from or toward each other, in order to adapt the machine for cultivating rows which are wide apart or close together, each gang of cultivator blades running between a central row of plants and an outer flanking row of the same, and these lateral adjustments can be efiected without materially varying the relation of the cultivator blades of each gang in respect to one another or to the pivot pin 9 constituting the pin on which the members 5 and 6 swing, the only effect of the adjustment being to narrow or widen the open end of the V presented by said members 5 and 6, and to cause a slight for ward or rearward movement of the pivot pin 9.

The members of the outer bar of each pair are readily .detachable by removing the rear pivot pin 9 and releasing the inwardly bent end of the forward member of the outer bar from the clamping slide 24: and the front and rear members of theinner'bar of each pair can then be secured in rigid angular relation to one another by tightening the 1.
